So do you believe in democracy or not? And I do not mean this as a loaded question because the value of democracy is a legitimately arguable point. If the majority of Californians want caps on property tax, then I do not see a good argument that they should not get it that is also compatible with democracy.
If you put a question to the electorate like 'should we tax only people whose last name begins with an X, Y or Z?', it's liable to pass.
Nobody really advocates for Direct Democracy. It isn't viable: 'tyranny of the majority' etc.
Most Western governments are Liberal Democracies - where some issues aren't subject to a vote - partly so that the mob can't persecute outnumbered subgroups.
Democracy != Direct voting.
It’s never meant that.
So people can “believe” in Democracy just fine and still think direct voting is bad.
Also, Democracy doesn’t even mean “if a majority of people believe X, therefore X”.
Democracy can mean a lot of things: direct, representative, etc. Voting for yourself is different from voting for your constituents. Ideally, the latter will also consider community effects.
